Under typical Central European summer conditions (Tmod ~65°C), this translates to approximately 1.5–2% higher energy yield compared to a PERC-based system of identical rated power. - **Bifacial Double-Glass Construction — 80% Bifacial Ratio** - The dual-glass 2+2 mm laminate with an 80% bifacial ratio enables an additional 5–30% energy yield from ground-reflected irradiance (albedo), depending on surface type. The glass-glass structure effectively eliminates microcracks and PID corrosion risk compared to conventional backsheet modules, extending the mechanical service life of the installation. - **30-Year Linear Power Warranty** - The manufacturer provides a 30-year linear power warranty, which reduces project risk in typical discounted cash flow models for non-recourse financing. While most peer comparables in this power class (610–635 Wp) offer equivalent 30-year warranty terms, DAS Solar backs its commitment with four consecutive quarters of BNEF Tier 1 status (Q1–Q4 2025). - **BNEF Tier 1 and PVEL Top Performer 2024** - DAS Solar has maintained BNEF Tier 1 standing for four consecutive quarters in 2025, confirming the bankability required for utility-scale PV project financing. Independently, Kiwa PVEL awarded DAS Solar Top Performer status in the 2024 PV Module Reliability Scorecard, providing objective third-party verification of module reliability beyond manufacturer claims. - **High Module Power Output — 610–635 Wp** - The 610–635 Wp power range in a 156-cell format (2,465×1,134 mm) reduces the module count required to reach a given system capacity, lowering BoS costs (cabling, racking, and labor) and, in turn, LCOE. The series is directly competitive on output with the Longi Hi-MO X10 Explorer (max. 635 Wp) and the Jinko Tiger Neo 66HL4M (max. 635 Wp). ## Cons - **Efficiency Trails Segment Leaders** - The series peaks at 22.7% module efficiency, while direct peer comparables — the Longi Hi-MO X10 Explorer LR7-72HVD and the Jinko Tiger Neo 66HL4M — reach 23.5% and 23.51%, respectively. The ~0.8 percentage-point gap means approximately 3.5% more modules or a proportionally larger roof or ground area are required for the same installed capacity, a meaningful constraint on space-limited projects. - **Limited Market Track Record** - DAS Solar was founded in 2018, giving it roughly 7 years of market presence compared to 25 years for Longi (est. 2000) and 19 years for Jinko (est. 2006). The absence of long-term field degradation data predating 2018 makes independent verification of stated annual degradation rates difficult, which may represent a risk factor when modeling 30-year project cash flows. ## About this series The DAS-DH156NA series are advanced bifacial modules that set efficiency standards through the use of **N-type cells in TOPCon technology**. This solution effectively eliminates light-induced degradation, guaranteeing investors stable energy production for decades. The **bifacial double-glass** design allows for the efficient use of reflected radiation, which, combined with high cell efficiency, drastically increases the total energy yield, especially on ground-mounted farms and light-colored roofs. These models are characterized by an **exceptionally low temperature coefficient**, allowing them to maintain high efficiency even in full sun and at high ambient temperatures. The robust double-glass construction provides **enhanced mechanical resistance** to harsh weather conditions, protecting the installation from micro-cracks and chemical corrosion. The DAS-DH156NA series is primarily dedicated to large commercial projects and photovoltaic farms, where **achieving the lowest LCOE** is crucial. It stands out from the competition with its excellent low-light performance and significantly slower power degradation over time, making it one of the most predictable and safe components for modern energy in Poland. ## Notable figures - At 22.5% efficiency, this panel is on par with typical \*\*TOPCon 600-650W\*\* modules - Power density of 225.4 W/m² matches the \*\*TOPCon 600-650W\*\* median - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 600-650W\*\* panels - At 34.3 kg (1.6 kg above \*\*TOPCon 600-650W\*\* median of 32.7 kg), requires checking roof load capacity - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof ## Questions ### What power output and efficiency do the DAS Solar DAS-DH156NA panels achieve? The DAS-DH156NA series delivers a peak power output of up to 635 Wp in the variant available on the Polish market, with module efficiency reaching up to 23.3%. This performance is made possible by N-type TOPCon cells, which offer a higher power density than older PERC technology. For the investor, this translates into more energy generated from the same roof or ground area. ### Are the DAS-DH156NA panels suitable for pitched roofs, or are they intended primarily for ground-mounted systems? The DAS-DH156NA series was designed primarily for large-scale photovoltaic farms and commercial installations. The module's large dimensions (2465 × 1134 × 35 mm) and considerable weight make transportation on a steep roof and installation on typical residential racking structures challenging. Smaller modules are better suited for pitched roofs. The DAS-DH156NA, however, delivers excellent results in ground-mounted systems or on flat industrial rooftops. ### What are the benefits of bifacial technology in the DAS-DH156NA series, and how much additional energy can be generated? The bifacial double-glass construction allows DAS-DH156NA modules to capture solar irradiance from both the front and the rear of the panel by utilizing albedo reflected from the ground surface. The bifaciality factor reaches up to 80%, which according to the manufacturer's data translates into up to 30% more energy compared to a conventional monofacial module. The gain is highest over high-albedo surfaces such as gravel, light-colored concrete, or snow. ### What warranty does DAS Solar offer on the DAS-DH156NA panels? The manufacturer provides a 15-year product warranty covering material and manufacturing defects, along with a 30-year linear power output warranty. Annual degradation after the first year does not exceed 0.40%, meaning the module retains at least 87.4% of its nominal power after 30 years. This is one of the strongest degradation figures in the industry and a direct argument for a low LCOE throughout the entire system lifecycle. ### How do the DAS-DH156NA panels perform under high temperatures in summer? The N-type TOPCon cells used in the DAS-DH156NA series feature an exceptionally low power temperature coefficient of approximately -0.30%/°C. By comparison, older PERC cells typically reach values around -0.35%/°C. This means that on hot days, when module temperature exceeds 70°C, the DAS-DH156NA loses less power than previous-generation technologies, directly increasing summer energy yields. ### Is DAS Solar a reputable manufacturer, and does the DAS-DH156NA series hold the relevant certifications? DAS Solar (Zhejiang Quzhou Das Solar Co., Ltd.) is classified as a Tier 1 manufacturer by Bloomberg NEF, confirming its financial strength and production capacity. The DAS-DH156NA series holds IEC 61215 and IEC 61730 certifications, and the manufacturer states that the modules have passed durability tests conducted to triply-reinforced requirements under the latest IEC standards. The company is headquartered in China and operates globally, including on the Polish market. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Datasheet_DAS-DH156NA-EN-615-6352465-1134-35-e7891087525e.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +2.7 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +50 W, lighter, +2.7 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +45 W, lighter, +2.5 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +2.5 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +40 W, lighter, +2.3 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +40 W, lighter, +2.3 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, lighter, +2.3 pp | | [DAS Solar DAS-DH156NA-610](https://comparepv.com/panel/das-solar-das-dh156na-610) | 610 W | -20 W, -0.7 pp | | [DAS Solar DAS-DH156NA-615](https://comparepv.com/panel/das-solar-das-dh156na-615) | 615 W | -15 W, -0.5 pp | | [DAS Solar DAS-DH156NA-620](https://comparepv.com/panel/das-solar-das-dh156na-620) | 620 W | -10 W, -0.3 pp | | [DAS Solar DAS-DH156NA-625W](https://comparepv.com/panel/das-solar-das-dh156na-625w) | 625 W | Very close match | | [DAS Solar DAS-DH156NA-635W](https://comparepv.com/panel/das-solar-das-dh156na-635w) | 635 W | Very close match | | [DAS Solar DAS-DH156NA-640W](https://comparepv.com/panel/das-solar-das-dh156na-640w) | 640 W | +10 W, +0.4 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +70 W, cooler, +2.5 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +65 W, cooler, +2.4 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | +40 W, cooler, +2.3 pp | --- Source: https://comparepv.com/panel/das-solar-das-dh156na-630 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
